FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wirelesscommunication and to techniques and apparatuses for resource selectionin an anchor-client network.

BACKGROUND

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, or the like). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless network may include a number of base stations (BSs) that cansupport communication for a number of user equipment (UEs). A UE maycommunicate with a BS via the downlink and uplink. The downlink (orforward link) refers to the communication link from the BS to the UE,and the uplink (or reverse link) refers to the communication link fromthe UE to the BS. As will be described in more detail herein, a BS maybe referred to as a Node B, a gNB, an access point (AP), a radio head, atransmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, or thelike.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent user equipment to communicate on a municipal, national,regional, and even global level. NR, which may also be referred to as5G, is a set of enhancements to the LTE mobile standard promulgated bythe 3GPP. NR is designed to better support mobile broadband Internetaccess by improving spectral efficiency, lowering costs, improvingservices, making use of new spectrum, and better integrating with otheropen standards using orthogonal frequency division multiplexing (OFDM)with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDMand/or SC-FDM (e.g., also known as discrete Fourier transform spreadOFDM (DFT-s-OFDM)) on the uplink (UL), as well as supportingbeamforming, multiple-input multiple-output (MIMO) antenna technology,and carrier aggregation. As the demand for mobile broadband accesscontinues to increase, further improvements in LTE, NR, and other radioaccess technologies remain useful.

Various aspects of the disclosure are described more fully hereinafterwith reference to the accompanying drawings. This disclosure may,however, be embodied in many different forms and should not be construedas limited to any specific structure or function presented throughoutthis disclosure. Rather, these aspects are provided so that thisdisclosure will be thorough and complete, and will fully convey thescope of the disclosure to those skilled in the art. Based on theteachings herein, one skilled in the art should appreciate that thescope of the disclosure is intended to cover any aspect of thedisclosure disclosed herein, whether implemented independently of orcombined with any other aspect of the disclosure.

It should be understood that any aspect ofthe disclosure disclosed herein may be embodied by one or more elementsof a claim.

Several aspects of telecommunication systems will now be presented withreference to various apparatuses and techniques. These apparatuses andtechniques will be described in the following detailed description andillustrated in the accompanying drawings by various blocks, modules,components, circuits, steps, processes, algorithms, or the like(collectively referred to as “elements”). These elements may beimplemented using hardware, software, or combinations thereof. Whethersuch elements are implemented as hardware or software depends upon theparticular application and design constraints imposed on the overallsystem.

It should be noted that while aspects may be described herein usingterminology commonly associated with a 5G or NR radio access technology(RAT), aspects of the present disclosure can be applied to other RATs,such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).

FIG. 1 is a diagram illustrating an example of a wireless network 100,in accordance with various aspects of the present disclosure. Thewireless network 100 may be or may include elements of a 5G (NR) networkand/or an LTE network, among other examples. The wireless network 100may include a number of base stations 110 (shown as BS 110 a, BS 110 b,BS 110 c, and BS 110 d) and other network entities. A base station (BS)is an entity that communicates with user equipment (UEs) and may also bereferred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an accesspoint, a transmit receive point (TRP), or the like. Each BS may providecommunication coverage for a particular geographic area. In 3GPP, theterm “cell” can refer to a coverage area of a BS and/or a BS subsystemserving this coverage area, depending on the context in which the termis used.

A BS may provide communication coverage for a macro cell, a pico cell, afemto cell, and/or another type of cell. A macro cell may cover arelatively large geographic area (e.g., several kilometers in radius)and may allow unrestricted access by UEs with service subscription. Apico cell may cover a relatively small geographic area and may allowunrestricted access by UEs with service subscription. A femto cell maycover a relatively small geographic area (e.g., a home) and may allowrestricted access by UEs having association with the femto cell (e.g.,UEs in a closed subscriber group (CSG)). ABS for a macro cell may bereferred to as a macro BS. ABS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS. In the example shown in FIG. 1 , a BS 110 a may be a macro BSfor a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102b, and a BS 110 c may be a femto BS for a femto cell 102 c. A BS maysupport one or multiple (e.g., three) cells. The terms “eNB”, “basestation”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” maybe used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some aspects, the BSs may be interconnected to one anotherand/or to one or more other BSs or network nodes (not shown) in thewireless network 100 through various types of backhaul interfaces, suchas a direct physical connection or a virtual network, using any suitabletransport network.

Wireless network 100 may also include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (e.g., a BS or a UE) and send a transmission of the data to adownstream station (e.g., a UE or a BS). A relay station may also be aUE that can relay transmissions for other UEs. In the example shown inFIG. 1 , a relay BS 110 d may communicate with macro BS 110 a and a UE120 d in order to facilitate communication between BS 110 a and UE 120d. A relay BS may also be referred to as a relay station, a relay basestation, a relay, or the like.

In some aspects, the wireless network 100 may include one or morenon-terrestrial network (NTN) deployments in which a non-terrestrialwireless communication device may include a UE (referred to herein,interchangeably, as a “non-terrestrial UE”), a BS (referred to herein,interchangeably, as a “non-terrestrial BS” and “non-terrestrial basestation”), a relay station (referred to herein, interchangeably, as a“non-terrestrial relay station”), and/or the like. As used herein, “NTN”may refer to a network for which access is facilitated by anon-terrestrial UE, non-terrestrial BS, a non-terrestrial relay station,and/or the like.

The wireless network 100 may include any number of non-terrestrialwireless communication devices. A non-terrestrial wireless communicationdevice may include a satellite, a manned aircraft system, an unmannedaircraft system (UAS) platform, and/or the like. A satellite may includea low-earth orbit (LEO) satellite, a medium-earth orbit (MEO) satellite,a geostationary earth orbit (GEO) satellite, a high elliptical orbit(HEO) satellite, and/or the like. A manned aircraft system may includean airplane, helicopter, a dirigible, and/or the like. A UAS platformmay include a high-altitude platform station (HAPS), and may include aballoon, a dirigible, an airplane, and/or the like. A non-terrestrialwireless communication device may be part of an NTN that is separatefrom the wireless network 100. Alternatively, an NTN may be part of thewireless network 100. Satellites may communicate directly and/orindirectly with other entities in wireless network 100 using satellitecommunication. The other entities may include UEs (e.g., terrestrial UEsand/or non-terrestrial UEs), other satellites in the one or more NTNdeployments, other types of BSs (e.g., stationary and/or ground-basedBSs), relay stations, one or more components and/or devices included ina core network of wireless network 100, and/or the like.

Wireless network 100 may be a heterogeneous network that includes BSs ofdifferent types, such as macro BSs, pico BSs, femto BSs, relay BSs, orthe like. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impacts on interferencein wireless network 100. For example, macro BSs may have a high transmitpower level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relayBSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. Network controller 130 maycommunicate with the BSs via a backhaul. The BSs may also communicatewith one another, directly or indirectly, via a wireless or wirelinebackhaul. For example, in some aspects, the wireless network 100 may be,include, or be included in a wireless backhaul network, sometimesreferred to as an integrated access and backhaul (IAB) network. In anIAB network, at least one base station (e.g., base station 110) may bean anchor base station that communicates with a core network via a wiredbackhaul link, such as a fiber connection. An anchor base station mayalso be referred to as an IAB donor (or IAB-donor), a central entity, acentral unit, and/or the like. An IAB network may include one or morenon-anchor base stations, sometimes referred to as relay base stationsor IAB nodes (or IAB-nodes). The non-anchor base station may communicatedirectly with or indirectly with (e.g., via one or more non-anchor basestations) the anchor base station via one or more backhaul links to forma backhaul path to the core network for carrying backhaul traffic.Backhaul links may be wireless links. Anchor base station(s) and/ornon-anchor base station(s) may communicate with one or more UEs (e.g.,UE 120) via access links, which may be wireless links for carryingaccess traffic.

In some aspects, a radio access network that includes an IAB network mayutilize millimeter wave technology and/or directional communications(e.g., beamforming, precoding and/or the like) for communicationsbetween base stations and/or UEs (e.g., between two base stations,between two UEs, and/or between a base station and a UE). For example,wireless backhaul links between base stations may use millimeter wavesto carry information and/or may be directed toward a target base stationusing beamforming, precoding, and/or the like. Similarly, wirelessaccess links between a UE and a base station may use millimeter wavesand/or may be directed toward a target wireless node (e.g., a UE and/ora base station). In this way, inter-link interference may be reduced.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wirelessnetwork 100, and each UE may be stationary or mobile. A UE may also bereferred to as an access terminal, a terminal, a mobile station, asubscriber unit, a station, or the like. A UE may be a cellular phone(e.g., a smart phone), a personal digital assistant (PDA), a wirelessmodem, a wireless communication device, a handheld device, a laptopcomputer, a cordless phone, a wireless local loop (WLL) station, atablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook,a medical device or equipment, biometric sensors/devices, wearabledevices (smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart ring, smart bracelet)), anentertainment device (e.g., a music or video device, or a satelliteradio), a vehicular component or sensor, smart meters/sensors,industrial manufacturing equipment, a global positioning system device,or any other suitable device that is configured to communicate via awireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, sensors, meters,monitors, and/or location tags, that may communicate with a basestation, another device (e.g., remote device), or some other entity. Awireless node may provide, for example, connectivity for or to a network(e.g., a wide area network such as Internet or a cellular network) via awired or wireless communication link. Some UEs may be consideredInternet-of-Things (IoT) devices, and/or may be implemented as NB-IoT(narrowband internet of things) devices. Some UEs may be considered acustomer premises equipment (CPE). UE 120 may be included inside ahousing that houses components of UE 120, such as processor componentsand/or memory components. In some aspects, the processor components andthe memory components may be coupled together. For example, theprocessor components (e.g., one or more processors) and the memorycomponents (e.g., a memory) may be operatively coupled, communicativelycoupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular RAT andmay operate on one or more frequencies. A RAT may also be referred to asa radio technology, an air interface, or the like. A frequency may alsobe referred to as a carrier, a frequency channel, or the like. Eachfrequency may support a single RAT in a given geographic area in orderto avoid interference between wireless networks of different RATs. Insome cases, NR or 5G RAT networks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120e) may communicate directly using one or more sidelink channels (e.g.,without using a base station 110 as an intermediary to communicate withone another). For example, the UEs 120 may communicate usingpeer-to-peer (P2P) communications, device-to-device (D2D)communications, a vehicle-to-everything (V2X) protocol (e.g., which mayinclude a vehicle-to-vehicle (V2V) protocol or avehicle-to-infrastructure (V2I) protocol), and/or a mesh network. Inthis case, the UE 120 may perform scheduling operations, resourceselection operations, and/or other operations described elsewhere hereinas being performed by the base station 110.

Devices of wireless network 100 may communicate using theelectromagnetic spectrum, which may be subdivided based on frequency orwavelength into various classes, bands, channels, or the like. Forexample, devices of wireless network 100 may communicate using anoperating band having a first frequency range (FR1), which may span from410 MHz to 7.125 GHz, and/or may communicate using an operating bandhaving a second frequency range (FR2), which may span from 24.25 GHz to52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred toas mid-band frequencies. Although a portion of FR1 is greater than 6GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 isoften referred to as a “millimeter wave” band despite being differentfrom the extremely high frequency (EHF) band (30 GHz-300 GHz) which isidentified by the International Telecommunications Union (ITU) as a“millimeter wave” band. Thus, unless specifically stated otherwise, itshould be understood that the term “sub-6 GHz” or the like, if usedherein, may broadly represent frequencies less than 6 GHz, frequencieswithin FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz).Similarly, unless specifically stated otherwise, it should be understoodthat the term “millimeter wave” or the like, if used herein, may broadlyrepresent frequencies within the EHF band, frequencies within FR2,and/or mid-band frequencies (e.g., less than 24.25 GHz). It iscontemplated that the frequencies included in FR1 and FR2 may bemodified, and techniques described herein are applicable to thosemodified frequency ranges.

As indicated above, FIG. 1 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 1 .

FIG. 2 is a diagram illustrating an example 200 of a base station 110 incommunication with a UE 120 in a wireless network 100, in accordancewith various aspects of the present disclosure. Base station 110 may beequipped with T antennas 234 a through 234 t, and UE 120 may be equippedwith R antennas 252 a through 252 r, where in general T≥1 and R≥1.

At base station 110, a transmit processor 220 may receive data from adata source 212 for one or more UEs, select one or more modulation andcoding schemes (MCS) for each UE based at least in part on channelquality indicators (CQIs) received from the UE, process (e.g., encodeand modulate) the data for each UE based at least in part on the MCS(s)selected for the UE, and provide data symbols for all UEs. Transmitprocessor 220 may also process system information (e.g., for semi-staticresource partitioning information (SRPI)) and control information (e.g.,CQI requests, grants, and/or upper layer signaling) and provide overheadsymbols and control symbols. Transmit processor 220 may also generatereference symbols for reference signals (e.g., a cell-specific referencesignal (CRS) or a demodulation reference signal (DMRS)) andsynchronization signals (e.g., a primary synchronization signal (PSS) ora secondary synchronization signal (SSS)). A transmit (TX)multiple-input multiple-output (MIMO) processor 230 may perform spatialprocessing (e.g., precoding) on the data symbols, the control symbols,the overhead symbols, and/or the reference symbols, if applicable, andmay provide T output symbol streams to T modulators (MODs) 232 a through232 t. Each modulator 232 may process a respective output symbol stream(e.g., for OFDM) to obtain an output sample stream. Each modulator 232may further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal. Tdownlink signals from modulators 232 a through 232 t may be transmittedvia T antennas 234 a through 234 t, respectively.

At UE 120, antennas 252 a through 252 r may receive the downlink signalsfrom base station 110 and/or other base stations and may providereceived signals to demodulators (DEMODs) 254 a through 254 r,respectively. Each demodulator 254 may condition (e.g., filter, amplify,downconvert, and digitize) a received signal to obtain input samples.Each demodulator 254 may further process the input samples (e.g., forOFDM) to obtain received symbols. A MIMO detector 256 may obtainreceived symbols from all R demodulators 254 a through 254 r, performMIMO detection on the received symbols if applicable, and providedetected symbols. A receive processor 258 may process (e.g., demodulateand decode) the detected symbols, provide decoded data for UE 120 to adata sink 260, and provide decoded control information and systeminformation to a controller/processor 280. The term“controller/processor” may refer to one or more controllers, one or moreprocessors, or a combination thereof. A channel processor may determinea reference signal received power (RSRP) parameter, a received signalstrength indicator (RSSI) parameter, a reference signal received quality(RSRQ) parameter, and/or a channel quality indicator (CQI) parameter,among other examples. In some aspects, one or more components of UE 120may be included in a housing 284.

Network controller 130 may include communication unit 294,controller/processor 290, and memory 292. Network controller 130 mayinclude, for example, one or more devices in a core network. Networkcontroller 130 may communicate with base station 110 via communicationunit 294.

Antennas (e.g., antennas 234 a through 234 t and/or antennas 252 athrough 252 r) may include, or may be included within, one or moreantenna panels, antenna groups, sets of antenna elements, and/or antennaarrays, among other examples. An antenna panel, an antenna group, a setof antenna elements, and/or an antenna array may include one or moreantenna elements. An antenna panel, an antenna group, a set of antennaelements, and/or an antenna array may include a set of coplanar antennaelements and/or a set of non-coplanar antenna elements. An antennapanel, an antenna group, a set of antenna elements, and/or an antennaarray may include antenna elements within a single housing and/orantenna elements within multiple housings. An antenna panel, an antennagroup, a set of antenna elements, and/or an antenna array may includeone or more antenna elements coupled to one or more transmission and/orreception components, such as one or more components of FIG. 2 .

On the uplink, at UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (e.g., forreports that include RSRP, RSSI, RSRQ, and/or CQI) fromcontroller/processor 280. Transmit processor 264 may also generatereference symbols for one or more reference signals. The symbols fromtransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by modulators 254 a through 254 r (e.g.,for DFT-s-OFDM or CP-OFDM) and transmitted to base station 110. In someaspects, a modulator and a demodulator (e.g., MOD/DEMOD 254) of the UE120 may be included in a modem of the UE 120. In some aspects, the UE120 includes a transceiver. The transceiver may include any combinationof antenna(s) 252, modulators and/or demodulators 254, MIMO detector256, receive processor 258, transmit processor 264, and/or TX MIMOprocessor 266.

As indicated above, FIG. 2 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 2 .

FIG. 3 is a diagram illustrating an example 300 of sidelinkcommunications, in accordance with various aspects of the presentdisclosure.

As shown in FIG. 3 , a first UE 305-1 may communicate with a second UE305-2 (and one or more other UEs 305) via one or more sidelink channels310. The UEs 305-1 and 305-2 may communicate using the one or moresidelink channels 310 for P2P communications, D2D communications, V2Xcommunications (e.g., which may include V2V communications, V2Icommunications, and/or the like), mesh networking, and/or the like. Insome aspects, the UEs 305 (e.g., UE 305-1 and/or UE 305-2) maycorrespond to one or more other UEs described elsewhere herein, such asUE 120. In some aspects, the one or more sidelink channels 310 may use aPC5 interface and/or may operate in a high frequency band (e.g., the 5.9GHz band). Additionally, or alternatively, the UEs 305 may synchronizetiming of transmission time intervals (TTIs) (e.g., frames, subframes,slots, symbols, and/or the like) using global navigation satellitesystem (GNSS) timing.

As further shown in FIG. 3 , the one or more sidelink channels 310 mayinclude a physical sidelink control channel (PSCCH) 315, a physicalsidelink shared channel (PSSCH) 320, and/or a physical sidelink feedbackchannel (PSFCH) 325. The PSCCH 315 may be used to communicate controlinformation, similar to a physical downlink control channel (PDCCH)and/or a physical uplink control channel (PUCCH) used for cellularcommunications with a base station 110 via an access link or an accesschannel. The PSSCH 320 may be used to communicate data, similar to aphysical downlink shared channel (PDSCH) and/or a physical uplink sharedchannel (PUSCH) used for cellular communications with a base station 110via an access link or an access channel. For example, the PSCCH 315 maycarry sidelink control information (SCI) 330, which may indicate variouscontrol information used for sidelink communications, such as one ormore resources (e.g., time resources, frequency resources, spatialresources, and/or the like) where a transport block (TB) 335 may becarried on the PSSCH 320. The TB 335 may include data. The PSFCH 325 maybe used to communicate sidelink feedback 340, such as hybrid automaticrepeat request (HARQ) feedback (e.g., acknowledgement or negativeacknowledgement (ACK/NACK) information), transmit power control (TPC), ascheduling request (SR), and/or the like.

In some aspects, the one or more sidelink channels 310 may use resourcepools. For example, a scheduling assignment (e.g., included in SCI 330)may be transmitted in sub-channels using specific resource blocks (RBs)across time. In some aspects, data transmissions (e.g., on the PSSCH320) associated with a scheduling assignment may occupy adjacent RBs inthe same subframe as the scheduling assignment (e.g., using frequencydivision multiplexing). In some aspects, a scheduling assignment andassociated data transmissions are not transmitted on adjacent RBs.

In some aspects, a UE 305 may operate using a transmission mode whereresource selection and/or scheduling is performed by the UE 305 (e.g.,rather than a base station 110). In some aspects, the UE 305 may performresource selection and/or scheduling by sensing channel availability fortransmissions. For example, the UE 305 may measure a received signalstrength indicator (RSSI) parameter (e.g., a sidelink-RSSI (S-RSSI)parameter) associated with various sidelink channels, may measure areference signal received power (RSRP) parameter (e.g., a PSSCH-RSRPparameter) associated with various sidelink channels, may measure areference signal received quality (RSRQ) parameter (e.g., a PSSCH-RSRQparameter) associated with various sidelink channels, and/or the like,and may select a channel for transmission of a sidelink communicationbased at least in part on the measurement(s).

Additionally, or alternatively, the UE 305 may perform resourceselection and/or scheduling using SCI 330 received in the PSCCH 315,which may indicate occupied resources, channel parameters, and/or thelike. Additionally, or alternatively, the UE 305 may perform resourceselection and/or scheduling by determining a channel busy rate (CBR)associated with various sidelink channels, which may be used for ratecontrol (e.g., by indicating a maximum number of resource blocks thatthe UE 305 can use for a particular set of subframes).

In the transmission mode where resource selection and/or scheduling isperformed by a UE 305, the UE 305 may generate sidelink grants, and maytransmit the grants in SCI 330. A sidelink grant may indicate, forexample, one or more parameters (e.g., transmission parameters) to beused for an upcoming sidelink transmission, such as one or more resourceblocks to be used for the upcoming sidelink transmission on the PSSCH320 (e.g., for TBs 335), one or more subframes to be used for theupcoming sidelink transmission, a modulation and coding scheme (MCS) tobe used for the upcoming sidelink transmission, and/or the like. In someaspects, a UE 305 may generate a sidelink grant that indicates one ormore parameters for semi-persistent scheduling (SPS), such as aperiodicity of a sidelink transmission. Additionally, or alternatively,the UE 305 may generate a sidelink grant for event-driven scheduling,such as for an on-demand sidelink message.

As indicated above, FIG. 3 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 3 .

FIG. 4 is a diagram illustrating an example 400 of sidelinkcommunications and access link communications, in accordance withvarious aspects of the present disclosure.

As shown in FIG. 4 , a transmitter (Tx)/receiver (Rx) UE 405 and anRx/Tx UE 410 may communicate with one another via a sidelink, asdescribed above in connection with FIG. 3 . As further shown, in somesidelink modes, a base station 110 may communicate with the Tx/Rx UE 405via a first access link. Additionally, or alternatively, in somesidelink modes, the base station 110 may communicate with the Rx/Tx UE410 via a second access link. The Tx/Rx UE 405 and/or the Rx/Tx UE 410may correspond to one or more UEs described elsewhere herein, such asthe UE 120 of FIG. 1 . Thus, a direct link between UEs 120 (e.g., via aPC5 interface) may be referred to as a sidelink, and a direct linkbetween a base station 110 and a UE 120 (e.g., via a Uu interface) maybe referred to as an access link. Sidelink communications may betransmitted via the sidelink, and access link communications may betransmitted via the access link. An access link communication may beeither a downlink communication (from a base station 110 to a UE 120) oran uplink communication (from a UE 120 to a base station 110).

As indicated above, FIG. 4 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 4 .

FIG. 5 is a diagram illustrating an example 500 of communications in anetwork, in accordance with various aspects of the present disclosure.As shown, a first wireless communication device (WCD 1), a secondwireless communication device (WCD 2), a third wireless communicationdevice (WCD 3), and a fourth wireless communication device (WCD 4) maycommunicate in a network. The network may be any type of network inwhich devices may communicate with other devices using beamformingtechniques. For example, the network may be a millimeter wave network.In some cases, the network may be a sidelink network and/or an IABnetwork, among other examples. In some aspects, one or more of the WCDsmay be, include, or be included in a UE, a base station, and/or an IABnode.

The WCD 1 may be scheduled to transmit a first future communication toWCD 4 using a beam 510. The beam 510 may include an expanding coveragearea (e.g., beam width) indicated by the area inside the two dashedarrows in FIG. 5 . A future communication is a communication that is tooccur at some time in the future. Other WCDs may be scheduled totransmit and/or receive future communications using beams within thecoverage area of the beam 510.

For example, as indicated in FIG. 5 , the WCD 2 may intend to receive asecond future communication. The WCD 2 and/or the device that istransmitting that second future communication to the WCD 2 may beconfigured to select resources to mitigate and/or minimize interferencebetween the first and second future communications. To facilitateavoidance of interference, WCDs may transmit announcements that indicatefuture communications. In some aspects, announcements may includetransmission (Tx) announcements (shown in FIG. 5 as “TxA”) that indicatea future transmission of a communication and/or reception (Rx)announcements (shown in FIG. 6 as “RxA”) that indicate a futurereception of a communication. TxAs and RxAs may indicate the resourcesthat will be used for the future communication.

For example, a transmission announcement may indicate a set of resourcesreserved for a future transmission of a communication. In some cases, atransmission announcement may be transmitted using a beam to be used totransmit the transmission that is indicated by the transmissionannouncement. In some cases, the transmission announcement may betransmitted using a beam that is wider than the beam to be used totransmit the transmission indicated by the transmission announcement. Inthis case, the transmission announcement may be used to facilitatepreventing a WCD within the coverage area from using resources, in adirection overlapped by the coverage area, that overlap resources usedby the WCD 1 to transmit the future communication. In some cases, thetransmission announcement may be transmitted as part of SCI. A nearbyWCD can receive the transmission announcement and, in response toreceiving the transmission announcement, can select resources and/orbeams that do not overlap those indicated in the announcement.

For example, as shown in FIG. 5 , the WCD 2 may intend, at leastinitially, to transmit and/or receive a communication using the beam520, which may have a coverage area that overlaps the coverage area ofthe beam 510. The WCD 2 may receive the transmission announcement and,in response to receiving the transmission announcement, may avoidcommunicating on the beam 520 (as indicated by the “X” over the beam520). In some cases, the WCD 2 may avoid communicating using resourcesindicated in the transmission announcement.

In some cases, the WCD 2 may provide a resource recommendation toanother WCD (e.g., WCD 3) that is based at least in part on thetransmission announcement. For example, as shown in FIG. 5 , the WCD 3may be receiving using a beam 530 that is directed away from the beam510 on which the transmission announcement is transmitted. As such, theWCD 3 may not receive the transmission announcement. However, the WCD 2may transmit a resource recommendation to the WCD 3 that indicates theresource information provided in the transmission announcement and/orthat suggests resources for the WCD 3 to use that avoid interferencewith the future communication.

In some cases, to facilitate reception of relevant transmissionannouncements, a WCD (e.g., WCD 2) may monitor for transmissionannouncements using a beam that the WCD intends to use to transmit orreceive a communication. In some cases, to further facilitate avoidanceof interference, a WCD that intends to receive a communication maymonitor for transmission announcements. Similarly, a WCD that intends totransmit a communication may monitor for reception announcements.

As indicated above, FIG. 5 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 5 .

FIG. 6 is a diagram illustrating an example 600 of communications in anetwork, in accordance with various aspects of the present disclosure.As shown, a first wireless communication device (WCD 1), a secondwireless communication device (WCD 2), a third wireless communicationdevice (WCD 3), and a fourth wireless communication device (WCD 4) maycommunicate in a network. The network may be any type of network inwhich devices may communicate with other devices using beamformingtechniques. For example, the network may be a millimeter wave network.In some cases, the network may be a sidelink network and/or an IABnetwork, among other examples. In some aspects, one or more of the WCDsmay be, include, or be included in a UE, a base station, and/or an IABnode. In some cases, the WCDs may be the WCDs depicted in FIG. 5 .

The WCD 2 may be scheduled to receive a first future communication fromWCD 4 using a beam 610. The beam 610 may include an expanding coveragearea (e.g., beam width) indicated by the area inside the two dashedarrows in FIG. 6 . Other WCDs may be scheduled to transmit and/orreceive future communications using beams within the coverage area ofthe beam 610.

For example, as indicated in FIG. 6 , the WCD 1 may intend to transmit asecond future communication. The WCD 1 and/or the device that isreceiving that second future communication from the WCD 1 may beconfigured to select resources to mitigate and/or minimize interferencebetween the first and second future communications. To facilitateavoidance of interference, WCDs may transmit announcements that indicatefuture communications. In some aspects, for example, a receptionannouncement (shown as “RxA”) may indicate a set of resources reservedfor a future reception of a communication. In some cases, a receptionannouncement may be transmitted using a beam to be used to receive thecommunication that is indicated by the reception announcement. In somecases, the reception announcement may be transmitted using a beam thatis wider than the beam to be used to receive the communication indicatedby the reception announcement. In this case, the reception announcementmay be used to facilitate preventing a WCD within the coverage area fromusing resources, in a direction overlapped by the coverage area, thatoverlap resources used by the WCD 2 to receive the future communication.In some cases, the reception announcement may be transmitted as part ofa PSFCH or similar channel. A nearby WCD can receive the receptionannouncement and, in response to receiving the reception announcement,can select resources and/or beams that do not overlap those indicated inthe announcement.

For example, as shown in FIG. 6 , the WCD 1 may intend, at leastinitially, to transmit and/or receive a communication using the beam620, which may have a coverage area that overlaps the coverage area ofthe beam 610. The WCD 1 may receive the reception announcement and, inresponse to receiving the reception announcement, may avoidcommunicating on the beam 620 (as indicated by the “X” over the beam620). In some cases, the WCD 1 may avoid communicating using resourcesindicated in the reception announcement.

In some cases, the WCD 2 may provide a resource recommendation toanother WCD (e.g., WCD 3) that is based at least in part on thereception announcement. For example, as shown in FIG. 6 , the WCD 3 maybe receiving using a beam 630 that is directed away from the beam 610 onwhich the reception announcement is transmitted. As such, the WCD 3 maynot receive the reception announcement. However, the WCD 1 may transmita resource recommendation to the WCD 3 that indicates the resourceinformation provided in the reception announcement and/or that suggestsresources for the WCD 3 to use that avoid interference with the futurecommunication. In some cases, to facilitate reception of relevantreception announcements, a WCD (e.g., WCD 1) may monitor for receptionannouncements using a beam that the WCD intends to use to transmit orreceive a communication.

In some cases, a transmission announcement and/or reception announcementmay not be received by WCDs that should receive them (e.g., WCDs thatare scheduled to transmit and/or receive future communications that mayinterfere with a future communication transmitted and/or received by aWCD). Moreover, monitoring a channel for announcements may require alarge number of resources, thus reducing the number of resourcesavailable for communicating with other devices. To facilitate monitoringfor announcements while supporting communications between some devices,the network may be organized into an anchor-client network.

As indicated above, FIG. 6 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 6 .

FIG. 7 is a diagram illustrating an example 700 of communications in ananchor-client network, in accordance with various aspects of the presentdisclosure. As shown, a first anchor device (A1), a second anchor device(A2), a third anchor device (A3), a first client device (C1), a secondclient device (C2), a third client device (C3), a fourth client device(C4), a fifth client device (C5), and a sixth client device (C6) maycommunicate in a network. The network may be any type of network inwhich devices may communicate with other devices using beamformingtechniques. For example, the network may be a millimeter wave network.In some cases, the network may be a sidelink network and/or an IABnetwork, among other examples. In some aspects, one or more of the WCDsmay be, include, or be included in a UE, a base station, and/or an IABnode.

As indicated above, the network may include anchor devices (A1, A2, andA3) and client devices (C1, C2, C3, C4, C5, and C6). In the context ofthe subject matter disclosed herein, anchor devices and client devicesmay be defined with respect to one another. For example, an anchordevice may be a wireless communication device that communicates with oneor more client devices and one or more other anchor devices. A clientdevice is a wireless communication device that communicates only with anassociated anchor device. Anchor devices and client devices may be thesame types of devices (e.g., UEs, IAB nodes, and/or the like). Ananchor-client relationship between an anchor device and an associatedclient device may be determined based at least in part on a networktraffic condition. If a traffic condition changes, an anchor-clienttopology of the network also may change.

An anchor device may be aware of the resources being used by associatedclient devices to communicate but may not be aware of the resourcesbeing used by client devices that are associated with other anchordevices. A client device may be configured to monitor for announcements.Since a client device only communicates with its associated anchordevice, the client device may have more resources available formonitoring for announcements. In some cases, an anchor device maymonitor a channel for announcements, but this may reduce the number ofresources available to the anchor device to communicate with otherdevices.

In some implementations, a client device may communicate with only oneassociated anchor device, which may facilitate leaving resources freefor the client device to monitor for announcements. The anchor devicemay communicate with a number of associated client devices. A forwardlink is a communication link that supports a communication to betransmitted by an anchor device to an associated client device. Areverse link is a communication link that supports a communication to betransmitted by a client device to an associated anchor device.

For example, as shown in FIG. 7 , A1 may communicate with associatedclient devices C1, C2, and/or C3, as well as with A3. A3 may communicatewith associated client device C6, and A2 may communicate with associatedclient devices C4 and C5. Communications between anchor devices andtheir associated client devices may be impacted by other communicationsthat cause interference due to using overlapping resources (e.g., timeresources and/or frequency resources) and/or overlapping beams.

In FIG. 7 , for example, A3 may be scheduled to engage in a first futurecommunication 710 with C6, and A1 may be scheduled to engage in a secondfuture communication 720 with C3. So that the first and second futurecommunications 710 and 720 do not interfere with one another, the firstand second future communications 710 and 720 may be implemented so thatthe resource set used for the first future communication 710 isorthogonal to the resource set used for the second future communication720. A2 also may be scheduled to communicate with C4 and/or C5 and, as aresult, it may be beneficial for A3 to take into account any resourcesused for those communications as well. However, monitoring availablechannels for announcements associated with the second futurecommunication 720 may consume more resources than A3 is able to commit.Thus, announcements may be missed, thereby increasing the chance ofinterference occurring between the first and second futurecommunications 710 and 720. As a result, network performance may bedegraded, and resource consumption may be unnecessarily inefficient.

Some aspects of techniques and apparatuses described herein may providededicated resources for transmitting and/or receiving announcements. Forexample, in some aspects, a first wireless communication device (e.g.,an anchor device) may transmit an anchor status notification associatedwith a first future communication between the first wirelesscommunication device and a second wireless communication device. Theanchor status notification may indicate to a receiving wirelesscommunication device that the receiving wireless communication device isto transmit one or more announcements associated with a second futurecommunication that the receiving device is scheduled to perform. In someaspects, the first wireless communication device may receive anannouncement using at least one set of dedicated resources.

In this way, some aspects may facilitate providing dedicated resourcesfor receiving announcements. As the wireless communication devices canbe informed of the dedicated resources, announcements may be transmittedand received without requiring extensive monitoring and/or resourceconsumption. In some aspects, a client device may monitor a set ofdedicated resources for announcements and/or may transmit anannouncement, using another set of dedicated resources, on behalf of anassociated anchor. As a result, some aspects disclosed herein mayfacilitate efficient use of resources and/or increased networkperformance.

As indicated above, FIG. 7 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 7 .

FIG. 8 is a diagram illustrating an example 800 associated with resourceselection in an anchor-client network, in accordance with variousaspects of the present disclosure. As shown, a first WCD 805, a secondWCD 810, and a third WCD 815 may communicate in a network. The networkmay be any type of network in which devices may communicate with otherdevices using beamforming techniques. For example, the network may be amillimeter wave network. In some cases, the network may be a sidelinknetwork and/or an IAB network, among other examples. In some aspects,one or more of the WCDs 805, 810, and 815 may be, include, or beincluded in a UE, a base station, and/or an IAB node. In some aspects,the WCD 805 and the WCD 815 may include anchor devices, and the WCD 810may include a client device (e.g., a client device corresponding to theWCD 805).
